Im ready to buy an aftermarket aluminum intake for my 440 dart! Its a street car that may see some track time but i DO want it to be as quick as possible on the street. It has stock 452 heads currently but will go aluminum soon hopefully. Ok, i REALLY want the performer RPM so bad i can taste the aluminum!!, BUT, i run a thermoquad, and by the time i take the height of the RPM intake, plus the carb adapter plate, im almost posotive it will not fit under my flat hood, and i dont want to cut my hood. I wish i knew someone close by that i could borrow the RPM intake and just mock it up on my car to be sure, but i cant see spending 300 bucks to buy the intake with the chances it will fit being so low. SO, i need to figure out which one to get that will clear the hood. Ive read that intake shoot out and still cant decide. Im guessing its between the Torker 2 and the holley street dominator,,? Any opinions are greatly appreciated. I need to decide soon as i have a lead on both the SD and torker 2 right now used. Thanks!

Use the Holley Street Dominator! I've tested it back to back against the Edelbrock Performer RPM on a mid 11 sec 440 combo in a 3700 lb car and they ran almost identical.

I had an Indy intake that wouldn't fit under the hood a few years ago. I just measured the amount it was too tall and had that much milled off at a machine shop. Cost about $75 if I remember correctly. Since I didn't have the chance to run both, I don't know what,if any, the performance penalty might have been. Or maybe cut the top flange off the adapter and have it welded to the intake after having the intake cut down till it all fits under the hood.
And I have had good luck with the Holley intake, myself.
Master, again and still

If you have to run a spread bore and have to have a flat hood, without doing any machine work your choices are limited to whatever manifolds already have a spread bore flange. Like a stock '70s iron thing, a Performer non-rpm, or a Street Dominator.
The Performer non-rpm is good for a huge car like a C body but I don't think you need that.
The stock iron stuff, is stock iron stuff.
That leaves the street dominator as the best overall choice.

Maybe the Holley SD is the right choice. But honestly, I don't know how anyone can make any recommendations with virtually no information regarding the motor, car, and use details.
I can assure you that there is a point that the SD will measurably under perform a dual plane intake.
And, if your're really interested in not giving up performance, I'm not sure why the use of something other than a TQ is not a consideration.

I have no clue how a holley works. The engine is a .030 over 440, cast crank engine, stock 452 heads. Compression ratio is right at 9.4:1. MP 284/484 cam installed 4 degrees advanced. 3000 stall, stock iron intake, 3.23 gears FOR NOW..will be going to 3.55 or 3.91 in the near future.Initial timing is 18 and total 34. The thing makes crazy torque especially being in a lighter A-body, but wanting a little more up top. I will go with aluminum heads when money is saved up.

is that your opinion serious? You think it would be fine on the street when just cruising being a single plane and all? Didnt know if you are being serious or sarcastic because of my combo.. you have a healthy cam, some stall, a torquey motor in a lightish car and might go to a pretty steep gear...the SD makes sense. I've read that the M1 single plane is similar to the SD, maybe someone else can confirm for you...

You've basically got the old Direct Connection 13.5 second recipe. Before the M1 intakes were available, and before the name change to Mopar Performance....Chrysler recommended the Holley Street Dominator for this setup. No worries, that's the one you want for how you're using the car + it will support your future plans.

Just unsure being it IS a single plane and being used on the street, but many say that the way its made that it is still good on the low end side for the street..?
